BETA PHOTO: Topo. Black Flag climbs the groove to the right.
This is a fun easy slab. If it weren't for the easier section in the middle breaking the pitch up, I'd have to give it more than 2 stars. The rock quality is good and there are some interesting holds interspersed within the friction slabbin'.
Start uphill and left of Black Flag. Friction up to good quartz features and a bolt at about 20'. Continue up easier, runout slab (5.7R) to a cam placement. Move up steeper friction past 2 more bolts and follow the subtle groove up until it's possible to step right to the anchors on Black Flag. 175'
Climbs the slab just left of Black Flag
very light rack, including finger/hand sized cam. There is a longish runout above the first bolt. A running belay would likely work well here because of the low angle nature of the slab.
